The grade of natural graphite powder refers to the particle size of graphite powder, usually expressed in mesh size, with units of um (micrometers). Graphite powder can be divided into different specifications according to the different mesh sizes, some of which are as follows:
100 mesh: The coarsest particle size, suitable for casting molten iron, precision ceramics, and bearing materials.
150 mesh: Coarse particle size, suitable for refractory materials, graphite products, and lubricating oils.
200 mesh: Moderate particle size, suitable for carbon products, bearing materials, and paints.
325 mesh: mainly used for refractory materials, conductive materials, wear-resistant materials, lubricants, high-temperature sealing materials, graphite emulsion, etc.
600 mesh: mainly used for powder metallurgy, friction materials, lubricants, pencils, pigments, handicraft production, electrode production, etc. 800 mesh: mainly used for conductive materials, lubricants, refractory materials, high-temperature resistant materials, pencils, pigments, electrode production, etc.
1200 mesh: mainly used for high-purity graphite products, high-purity graphite in the electronics industry, as well as lubricants, pencils, pigments, electrode production, etc.
2000 mesh: mainly used for high-purity graphite products, high-purity graphite in the electronics industry, graphite paper, lubricants, pencils, pigments, electrode production, etc.
The higher the mesh size of graphite powder, the finer its particles, making it more suitable for high-precision application scenarios. At the same time, different application scenarios also have different requirements for the purity, particle size, shape, etc. of graphite powder. Therefore, when selecting graphite powder, it is necessary to choose according to actual needs.
